In November 2011, Valve admitted that its Steam forums were hacked, and some user data including encrypted credit card information and hashed passwords were stolen, and that pending investigation, it asked users to change their Steam passwords. Valve noted that at that time, it had not seen any evidence of encrypted data being hacked. Today, Valve issued an update to all its Steam members via e-mail, where it notified them that investigation is still in progress, that Valve is taking help of external agencies to investigate, and that it still sees no evidence of encrypted credit card data being tampered with. As a note of caution, though, it asked users to keep an eye on their credit card activity and statements.

That credit card data is encrypted to hell and back--very little chance they will be able to unencrypt it and reassemble it. It is possible but, at best, they'll get just a handle of cards--definitely not all the users.

The only kind of purchase that won't overdraw your account is if it's swiped physically. Making purchases online and EFT's will still overdraw your account. How do I know? I accidentally overdrew my account with an online purchase even though I used my debit card. They refunded me the charge because of a misunderstanding, but the new regulation clearly states it only prevents overdraws from an actual swipe of the card.

Edit: Also, as far as I know this is a standard regulation set down by the government. It's part of the opt-in/opt-out overdraw legislature.

That depends on the bank. I have my account set up the same as you, however, my bank will not allow it to get overdrawn regardless of whether iys physically swiped oe used online. Only caveat, any auto payments will still go through. Auto payments such as a recurring bill that comes out that you specifically setup through the bank. Steam and paypal do not apply to the autopay definition..
